Children with Conduct Disorder are in denial. They tend to minimize their problems and blame others for their misbehavior and failures. This shifting of guilt justifies, as far as they are concerned, their invariably and pervasively aggressive, bullying, intimidating, and menacing gestures and tantrums. Adolescents with Conduct Disorder are often embroiled in fights, both verbal and physical. They frequently use weapons, purchased or improvised (e.g., broken glass) and they are cruel. Many underage muggers, extortionists, purse-snatchers, rapists, robbers, shoplifters, burglars, arsonists, vandals, and animal torturers are diagnosed with Conduct Disorder.
